Molycorp (MCP+13%) is among today's top gainers on news that its California facility had begun to produce heavy rare-earth concentrate from freshly mined ore and is on track to achieve full Phase 1 production rates in Q4. But Paul Ausick reminds that by next year, the supply of rare earths will more than double the amount now on the market, and some companies are developing substitutes.

Being long I welcome the 13% rise. What strikes me is that Paul Ausick reminds us that some companies are developing substututes.

I checked for a short time the internet concerning this topic an I found that GM has figured out a way to reduce its demand for dysprosium in its chevy volt and Philipps is acively looking for rare earth substitutes in LED lighting. Toyota is also quite acive.

What do we have to expect from here? Can REE-usage be reduced in a significant way. Do REE-prices have to go even lower to avoid that? What are the implications for REE-investmentes?
